Features: 1. The R307 Optical Fingerprint Module integrates a fingerprint algorithm chip with functions such as fingerprint enrollment, image processing, feature extraction, template generation, template storage, fingerprint comparison (1:1), and fingerprint search (1:N). 2. The fingerprint reader supports secondary development and can be embedded into various end products such as access control systems, attendance devices, safes, and car door locks. 3. Low power consumption, low cost, compact size, and excellent performance. 4. Professional optical technology and precise module manufacturing process. 5. Advanced image processing capability; capable of capturing images with up to 500 DPI resolution. 6. Built-in fingerprint detection function. Specification: Supply voltage: DC 4.2–6.0V Supply current: Working current: 50mA (typical) Peak current: 75mA Fingerprint image capture time: ≤ 1 second
